The purifying device 103 rotates the impeller under the driving of the motor, and sends the airflow to the purifying device 103 through the air outlet 106. The airflow is purified by the purifying device 103 and sent into the chamber.

Since the airflow brought by the rotation of the impeller is concentrated only on one air outlet 106, the wind pressure is large, and the airflow discharged from the air outlet 106 of the volute 105 is tapped on the purification device 103, which generates a large noise, and the wind pressure is also generated. When the larger airflow is discharged by the air purifying device 103, the wind speed is large, and the airflow is blown to the person in the room, which makes the person in the room feel uncomfortable, and the air cleaner 100 has only one out of the fan 104. At the tuyere 106, the amount of airflow is not large, so that people in the room feel that the wind is small, which is insufficient to meet the demand for air purification. The air ejector 100 adopts a larger volute 105 to collect and discharge the airflow brought by the rotation of the impeller, and the volume occupied by the volute 105 is large, so that the volume of the air cleaner 100 is large.
